The fine is 2000 baht if you miss one report or 20 and you’ll pay that if you ever need to visit the immigration office and it’s 1600 baht if you don’t have a current TM30
if your on a OA visa you won’t need to show funds until year 3 if you do it right unfortunately you’ll need insurance which isn’t a very good policy you can start bringing in the 65k a month and not need the 800k
